yfz hot cams (atv)

a friend of mine has a set of hot cams left over from his yfz450 race quad. Will they work in my 426? are they the same as the bike hot cams?

im pretty sure they will not. they have different part numbers.

I remember seeing someone here on TT using YFZ cams in his 426. If I remember correctly the power curve was so low that it was not worth the swop. I would contact Hot Cams to see what they say.

Yes they will work.

They will fit the engine, but the results may not be what you expect. The Quad starts out with cam timing similar to a WR, and low power output to match. Stock YZ450 cam timing is a fairly big hop-up for that engine, and if that's what's been done in the Hot Cams part for the quad, you could be disappointed in the return on your time and money. I'd suggest asking Hot Cams what they think.

      Got a break in the weather over the weekend, and was finally able to get out on a track for the first time since October.  I know I suck compared to a lot of guys (and kids for that matter), but I always have a blast twisting a grip and roosting some dirt!  Here's a raw uncut lap around the MX track at IMI Motorsports Complex in Dacono, CO.  Was a fun day despite some wind.  Also, there was a drift car club having a meet on the road course.  So, got to check out some drift car action while we were taking a break.

      Lightly used Clarke Gas Tank (model #11614) for a 2010-13 YZ450F.  Includes cap.  For fuel injected YZ450F, so needs to have fuel pump transferred over.  Rest of stock tank hardware fits perfectly.  2.8 gallon capacity, so great for desert, hare scrambles, or WORCS.  Retails for $240.
